    Abstract: An analyser plate (AP) between a projection system (PL) and a radiation sensor (DS) is illuminated by a beam of projection radiation. The analyser plate contains 2 crossing regions, each of which transmits radiation with a different polarisation direction. The beam of projection radiation is patterned without influencing the polarisation of the beam. By patterning the beam of projection radiation so that one region receives more radiation than the other region, the radiation sensor (DS) is given polarisation selectivity.
